Subject: [PATCH] Fix to keyspin escape function. The escape function is the
 feature that allows the user to call the 2nd softkey ( escapes the spin) and
 puts an entry so that the Current state is recovered.

git-svn-id: svn://10.0.0.236/branches/MOZILLA_1_8_BRANCH@201128 18797224-902f-48f8-a5cc-f745e15eee43
